Early autumn herbicide application in winter cereals is in many areas a reasonable agronomic procedure. ADDITION with the well-known active ingredients diflufenican (40 g/l) and pendimethalin (400 g/l) is a new combination for weed control in winter wheat, barley, rye and triticale. Early post emergence application of 2.5 l/ha includes these advantages: unrestricted selectivity to various application conditions for all kinds and varieties of winter cereals and wide efficacy spectrum to broad-leaved weeds. The specific feature of ADDITION is a complementary and overlapping efficacy spectrum. Within the overlapping spectrum diflufenican and pendimethalin affect the same weed varieties with different modes and on different sites of action. HRAC rates diflufenican to group F1 and pendimethalin to group K1. These different modes of action are the basis for variety specific resistance management. According to increasing discussions of weed resistance, ADDITION is a strong partner to set up a successful long term resistance management. Favorable restrictions are allowing a wide application range of ADDITION.
